And after that device shows up nmcli can be very useful:
nmcli device
will list your network devices
if it is not enabled - unless it it is physically switched off -
you can unblock it with
nmcli radio wifi on
and to connect
nmcli --ask dev wifi connect <your-network-ssid>
it will ask for your wpa password and by default will remember it.
